Built with Alexander Bublik
The current iteration in an ongoing development process with ATP professional Alexander Bublik. A checkpoint, not a conclusion.
The Development Process
Project Bublik is the story of an ongoing development process between Alexander Bublik and Diadem. It’s a working snapshot of the specs, feel, and construction being refined toward his eventual signature frame. With dozens of prototypes and thousands of design decisions, Project Bublik is a work-in-progress that players around the world get to participate in.
Most signature rackets are launched as finished products. We did the opposite. Project Bublik is a checkpoint along the way rather than a final conclusion.
Diadem and Bublik are building his frame the way he plays: entertaining, unconventional, and with a refusal to settle. Project Bublik captures that process mid-stride with current specs, current tuning, current feel. Never stagnant, always moving.
Welcome to Project Bublik
In his words
Doing things my way.
“Tennis, for me, has always been about doing things my way. So when I started working with Diadem to build my perfect racket, I wanted the same thing: something built exactly for how I play, with no compromises.
Project Bublik is the first step of that journey. It’s a frame we’ve developed together, tuned to my specs, my feel, my game.
It’s not finished yet. We’re still refining, still pushing, still chasing perfection. But I wanted you to be part of that process.”

From the Bench
Sketches, color references, tagged prototypes and frame studies from the builds behind this iteration.
The Range
This iteration comes in a Project Bublik Team 100, a full-weight 100 and a tighter-patterned 98. All are priced the same, so pick on feel rather than budget. Each card says who it suits; every number is in the specifications table below.
Choose this if you want the easiest of the range to swing, or you need a 4 (L0) grip. It is the only frame offered in that size.
$269.95
Choose this if you want the same head size and open pattern as the Team, with more weight behind the ball.
$269.95
Choose this if you want the smallest head, the tightest 16 × 20 pattern and the most head-light balance of the range.
